[0020] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0021] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0022] like Figure 1 As shown, an external ground power supply vehicle includes an AC input module, an overvoltage protection module, an AC / DC conversion module, an overvoltage and overcurrent protection module, an output module, a display module, a data processing module, an overheating control module, and a voltage setting module;

[0023] The AC input module, the overvoltage protection module, the AC-DC conversion module, the overvoltage and overcurrent protection module and the output module are sequentially connected; the display module, the overheat control module, the voltage setting module, the AC-DC conversion module and the overvoltage and overcurrent protection module are connected with the data processing module respectively.

[0024] The overheat control module comprises a plurality of temperature sensors, an analog-digital converter, a heat dissipation device and a heat dissipation device control module; the plurality of temperature sensors are connected with the analog-digital converter respectively, and the heat dissipation device is connected with the heat dissipation device control module; the analog-digital converter and the heat dissipation device control module are connected with the data processing module respectively.

[0025] The heat dissipation device comprises a plurality of heat dissipation fans, and the plurality of fans are connected with the heat dissipation device control module respectively.

[0026] The AC input module comprises a power input interface, and the power input interface is connected with the overvoltage protection module through a cable.

[0027] The overvoltage protection module adopts a high-voltage protector, the input end of the high-voltage protector is connected with the power input interface, and the output end of the high-voltage protector is connected with the AC-DC conversion module.

[0028] The AC-DC conversion module adopts a model AH896X.

[0029] The overvoltage and overcurrent protection module adopts a model WMZ13A.

[0030] The output module comprises an aviation plug, and the aviation plug is connected with the overvoltage and overcurrent protection module through a cable.

[0031] The voltage setting module comprises a data input module, and the data input module is connected with the data processing module.

[0032] The application provides an external ground power supply vehicle, which mainly comprises the following modules: an AC input module, an overvoltage protection module, an AC-DC conversion module, an overvoltage and overcurrent protection module, an output module, a display module, a data processing module, an overheat control module and a voltage setting module.

[0033] The AC input module is an energy inlet of the whole power supply vehicle, comprising a power input interface, which is connected with the overvoltage protection module through a cable. The module is designed with a dustproof and waterproof structure, which can ensure good electrical connection performance in various outdoor environments, and is equipped with a filter circuit to reduce the interference of noise in the power grid and improve the purity of input power.

[0034] The overvoltage protection module uses a high-voltage protector, whose input is connected to the power input interface and whose output is connected to the AC / DC converter module. The high-voltage protector monitors the input voltage in real time and automatically cuts off the power supply when the voltage exceeds a preset safety threshold, preventing equipment damage or safety incidents and ensuring stable operation of the power supply vehicle.

[0035] The AC / DC converter module is the core component of the power supply vehicle and utilizes the highly efficient AH896X conversion chip. This module converts incoming AC power into stable DC power with high efficiency, low losses, and excellent thermal stability. The AH896X chip incorporates a built-in intelligent control algorithm that automatically adjusts output power based on load conditions, maximizing energy utilization.

[0036] The overvoltage and overcurrent protection module uses a WMZ13A protector, connected between the AC / DC converter and the output module. This module not only effectively prevents output voltage or current from exceeding safe limits but also rapidly responds to detect an anomaly, shutting off output and protecting connected equipment from damage. The WMZ13A's high precision and rapid response make it a crucial component in ensuring output safety on power trucks.

[0037] The output module includes an aviation plug, which connects to the overvoltage and overcurrent protection module via a cable. The aviation plug is wear-resistant, waterproof, and dust-proof, making it suitable for harsh environments and ensuring stable and reliable power output. Furthermore, the output module supports a variety of output voltages and currents to meet the power needs of different devices.

[0038] The display module, connected to the data processing module, displays the power supply vehicle's operating status in real time, including key parameters such as input voltage, output voltage, current, power, and operating temperature. The high-definition LCD screen and user-friendly interface allow users to intuitively understand the vehicle's operating status and make timely adjustments.

[0039] The data processing module is the "brain" of the entire power supply vehicle, responsible for collecting and processing data from various sensors and controlling the operation of each module according to preset logic. This module uses a high-performance microprocessor with powerful computing capabilities and fast response speed, enabling comprehensive monitoring and intelligent management of the power supply vehicle.

[0040] The overheat control module consists of multiple temperature sensors, an analog-to-digital converter (ADC), a heat sink, and a heat sink control module. Temperature sensors are located in key locations within the power supply vehicle, monitoring temperature changes in real time. The ADC converts the analog signals into digital signals, which are then transmitted to the data processing module. When the temperature exceeds the safety limit, the data processing module activates the heat sink (e.g., multiple cooling fans) to enhance heat dissipation and prevent damage from overheating. The heat sink control module dynamically adjusts fan speed based on temperature fluctuations to achieve precise temperature control.

[0041] Specifically, such as Figure 2 As shown in the figure, the ground power supply vehicle is used to provide DC 27V power to the equipment under test during ground testing or repair.

[0042] To address the portability and maneuverability issues of ground power carts, this paper proposes an external ground power cart. This cart primarily consists of a body for loading the power supply and a cable reel for storing the cables. The reel also serves as a handle for easy movement. Furthermore, the cart's base features two universal wheels and two fixed wheels. The universal wheels facilitate movement, while the fixed wheels provide stability. The operator panel features a 30° tilt and a display, greatly facilitating manual operation.

[0043] The ground power supply vehicle consists of a customized vehicle body, DC power module, operation display panel, connectors, contactors, buttons, and cables. Figure 3 shown.

[0044] The power supply vehicle uses an AC-DC power supply module to achieve a DC 0~32V output.

[0045] The external AC input power supply of 380Vac / 50Hz is connected to the AC input socket of the power supply vehicle, connected to the overvoltage protection circuit of the input circuit through the AC input socket, and then connected to the AC / DC conversion circuit of the DC power supply module. The AC / DC is controlled by the control circuit and outputs according to the output voltage set by the user.

[0046] When the user sets the output voltage through the DC power module panel and starts the output, the control circuit detects the difference between the output DC voltage and the user-set voltage. If the output voltage is too high, the output control is adjusted to lower the output voltage; if the output voltage is too low, the output control is adjusted to increase the output voltage so that the output voltage is stable at the user-set value.

[0047] Input overvoltage protection: When the input voltage is too high, the overvoltage protection circuit will be activated and automatically cut off the input AC power, thereby protecting the power supply vehicle from damage.

[0048] Overheat protection: Equipped with a temperature detection function inside. When the internal part is overheated, the overheat protection circuit is activated to perform overheat protection and stop output.

[0049] Output overvoltage protection: When the output DC power supply is overvoltage, the overvoltage protection starts and stops the output.

[0050] Output overcurrent protection: When the output DC power is overcurrent, the overcurrent protection starts and stops the output.

[0051] Emergency stop: When an emergency occurs, press the emergency stop button to automatically cut off the input AC power and DC output.

[0052] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields.
